Summary
The adiabatic vertical velocity fields in the pressure coordinates were evaluated at the intervals of 200 mb in a vertical column extending from 1000 mb to 200 mb surface on a mesh covering Indian region. The computed adiabatic vertical velocity was used in the thermodynamic energy equation to obtain diabatic vertical velocity. The rainfall patterns were seen to be in agreement with rising motion. The computed diabatic vertical velocity is generally about an order of magnitude larger than adiabatic vertical velocity at each of the three levels viz., 800, 600 and 400 mb.
Zusammenfassung
Es wurden adiabatische Vertikalgeschwindigkeitsfelder in Druckkordinaten in Schichten von 200 mb von der 1000 mb-bis zur 200 mb-Fläche aus einem Indien überdeckenden Gittemetz abgeleitet. Mit der berechneten adiabatischen Vertikalgeschwindigkeit wird aus der thermodynamischen Energiegleichung die diabatische Vertikalgeschwindigkeit gewonnen. Die Niederschlagsverteilung zeigt eine Übereinstimmung mit den Gebieten mit aufsteigender Bewegung. Die berechnete diabatische Vertikalgeschwindigkeit ist in jedem der 800-, 600- und 400 mb-Niveaus um ungefähr eine Größenordnung größer als die adiabatische Vertikalgeschwindigkeit.
